So apparently Nintendo found out that some minors have been exchanging FCs on forums and using SwapNote to send each other lewd pictures without their parents knowing or something. In order to combat this, Big Brother N has straight-up disabled SwapNote SpotPass, meaning you can now only SwapNote by StreetPassing.

Thoughts? I personally haven't used the app since it came out, but the idea behind what's happening here is definitely interesting.
